Ninomiya, S. Kitano, T. Yoshida, T. Bandoh, D. Baatar, T. Matsumoto, S. Tsuboi] Background: Recently, the laparosonic coagulating shears (LCS) have been used widely in laparoscopic surgery. In the current study, the usefulness of LCS for arterial division and hemostasis was examined in porcine arteries. Methods: Porcine arteries of several diameters (1, 3, and 5 mm) were removed and divided using LCS with different blade modes: shear, blunt, and flat. The division time and bursting pressure were registered. Additionally, divided sections stained by the Azan-Mallory method were observed microscopically. Results: The division time was dependent on the blade modes used. With the flat mode, the bursting pressure of 5-mm arteries was significantly higher than the bursting pressure with shear and blunt modes. Histologically, cavitation and mild degeneration of the vessel walls occurred adjacent to the cutting edge. Conclusion: The LCS is a safe and useful device for arterial division and hemostasis for 5-mm arteries if an adequate blade mode is used.
